As Microsoft has decreed, that key sends LEFTMETA + LEFTSHIFT + F23
(usually across multiple frames) and the then the same in reverse when
released.
xkeyboard-config 2.44 maps this sequence by default to XF86Assistant but
for the use-cases where this does not work reshuffling the whole event
sequence is the best approach and that can easily be done with a plugin.
Note that this is the minimum effort plugin - it works for one
keyboard at at time (duplicate the plugin if two keyboards are needed,
or remove the vid/pid check) and it does *not* intercept the meta/shift
key presses and delay them, it simply releases them on F23 and then
replays the new sequence. Good enough for an example plugin.
Example sequence produces shift + a on press and releases a + shift on
release. Holding the key will thus produce AAAAAAAAA which is an
excellent summary of how this key was designed.

Add an option to enable autoloading plugins from the default paths.
This makes testing and adoption for new users easier as they can (if
necessary) rebuild libinput with that option enabled instead of having
to wait for the compositor stack to update.
Autoloading will only use the default paths (/etc and /usr/lib) and will
only happen if the client does not modify those paths since that implies
the client wants to load plugins themselves. A client that adds a plugin
path but doesn't load the plugins is considered buggy anyway.

The existence of the log global was in part due to early (pre-merge)
versions of the Lua plugins supporting multiple libinput plugin objects
per file. This is no longer the case and integrating the log functions
into the (single) libinput object makes the code more obvious (we're
calling libinput:log_debug() now, so it's obviously a libinput log
function) and we no longer mix dot with colon notations.

Injecting frame was the first implementation of adding event frames but
it has since effectively been replaced by append/prepend_frame which are
more predictable and easier to support.
In the Lua API injecting frames was only possible within the timer and
the only real use-case for this is to inject events that are then also
seen by other plugins. But that can be achieved by simply ordering the
plugin before the other plugins and using the append/prepend approach.
Until we have a real use-case for injecting events let's remove the API
so we don't lock ourselves into an API that may not do what it needs to
but needs to be supported for a long time.

A caller is likely to unconditionally call
libinput_tablet_tool_config_pressure_range_set() with whatever
values it has in its config storage. Those values will be 0 and 1 by
default, we should not take this as a sign that the tool has a pressure
range.
Setting a pressure range resets the automatic offset handling which we
definitely don't want to do for the default range.
Fixes: #1177
Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1340>
When a user configures a pressure range, the tool would get locked into
the current offset even if that offset was still pending. For example, a
sequence of
- tool in-prox with pressure 50%
- libinput_tablet_tool_config_pressure_range_set(tool, 0.0, 0.9)
- tool out-of-prox, tool-in-prox
- libinput applies the tool config, tool now has a configured range,
has_offset = true
- tool out-of-prox, tool-in-prox
- update_pressure_range() sees has_offset = true, scales the last offset
(50%) to the actual offset.
Fix this by resetting the detected offset to zero when we shortcut the
heuristics. A user-defined pressure range should include the tool's
pressure offset anyway, the user knows this much better than our
heuristics.

delta_time can be zero when:
- the fallback acceleration function is used for multiple movement types
(for example, pointer motion and wheel scrolling simultaneously)
- two different methods produce the same movement at the same time
(for example, button-scrolling and wheel-scrolling)
Reusing the last delta_time is a graceful fallback even if there are
duplicate events or event-ordering bugs.

Dispatch high-resolution scroll wheel events through filter_dispatch_scroll
so they can be accelerated using the custom acceleration profile.
Low-resolution scroll wheel events are not accelerated to avoid zero
delta-time in the filter.

A few changes to the Lua API didn't get reflected in the example
plugins, let's update them.
Also included here is naming of all arguments, instead of _ use the
argument name even where unused. These are examples so being expressive
is more important than making any lua static checkers happy.

"libinput_plugins_flags" is bound to be annoying to approximately
everyone who'll ever have to use them so let's rename this while we
still can. Renamed to libinput_plugin_system_flags to leave the
namespace open for a possible future libinput_plugin_flags that works
on individual plugins.

Python 3.14 has changed from fork to forkserver[1] which causes
libinput replay to fail with the following error when starting the
subprocesses:
ValueError: ctypes objects containing pointers cannot be pickled
This is caused by the libevdev device being passed to the sub process.
A more proper fix may be to only initialize the device in the subprocess
and then signal the process to start replaying. But meanwhile, switching
back to fork will do.

If a plugin adds events to an event frame that are not supported by the
target device we may eventually dereference a null pointer (for ABS_*
events) or, possibly, use an OOB index access (for buttons or keys).
Let's filter out any events that the device doesn't support immediately.
